Really interesting article. Nice read indeed. I always draw circles clockwise. Actually I can write in several different alphabets. Regardless of which hand I use. Just tested that. Latin/Cyril based ones on right hand. Clockwise. Arabic or Kanas on left hand and again clockwise. But I don't think starting point really matters. It's just muscle memory most of the time. Once you learn, you keep it. If it was different, It should be counter clockwise on left hand.
